Add them WHERE in the config?

I have installed the 32bit libraries and multilib compilers, and it turns out that neither the 32bit nor the 64bit libraries end up in the main /usr/lib directory that is mentioned in Makefile.PL.

In the perlbrew environment, running
cpanm XML::LibXML

still reports:

Configuring XML-LibXML-2.0019 ... N/A
! Configure failed for XML-LibXML-2.0019. See /home/emgrasso/.cpanm/wo
+rk/1375587018.8608/build.log for details

and /home/emgrasso/.cpanm/work/1375587018.8608/build.log says:

Try setting LIBS and INC values on the command line

If you install via RPMs, make sure you also install the -devel
RPMs, as this is where the headers (.h files) are.

I don't think it is talking about the cpanm command line.

The perlbrew environments don't seem to contain any CPAN directories for config files where I could set o conf makepl_arg. (Does cpanm pay attention to those? If so, what format would I need to use so Makefile.PL would search the existing paths at well as the special 32 or 64 bit paths?)
